TELEVISION ALIGNMENT TOOL Arthur C. Capelle, Bradenton, Fla. Original No. 2,817,985, dated December 31, 1957, Serial States Patent No. 481,539, January 13, 1955. Application for reissue October s, 1958, Serial No. 766,151

' 9 Claims. (c1. 813) Matter enclosed in heavy brackets II] appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

This invention relates generally to the class of tools and more particularly to a device especially adapted for utilization in the adjustment of control screws for television sets and the like.

The primary object of the present invention resides in the provision of an alignment tool having means for determining the change of position of an adjustment screw or the like independent of the number of separate turns in one direction or the other during the alignment pro- L cedures.

The construction of this invention features the utilization of a novel indexing member which is held by means of a resilient clip on a transparent index housing received over a cylindrical member having a grooved scale thereon which carries the shank of the blade.

' Still further objects and features of this invention reside in the provision of analignment tool that is simple in construction, highly efiicient in operation, and relatively inexpensive to manufacture, thereby permitting wide distribution and utilization.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this alignment tool, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:

blade 14 at the end thereof, or, as is shown in Figure 3, a shank 12 may be provided with a threaded end 16 for threaded engagement with a suction cup 18 or other suit able blade holder. The shanks 12 or 12' are receivable as can be best seen in Figures 3 and 4, in resilient washers 20 and 22 which themselves are received within a cylindrical member 24 to frictionally and resiliently hold the shank 12 for rotation with the cylindrical member 24. The cylindrical member 24 is provided with a spiral or helical groove 26 cut into the surface thereof as well as suitable indicia 28 and other indicia 30, the indicia-28 and 30 being disposed on the surface of the cylindrical member 24 and being arranged with respect to the groove 26 for indicating the position of the cylindrical member 24 with respect to a transparent index housing 32. The groove 26 and indicia 28 and 30 form a suitable scale The transparent index housing or sleeve 32 is concentrically disposed about the cylindrical member 24 and has an opening 34 therein for reception of a magnifying glass 36 which enables the indicia 28 and 30 to be readily observed to thus determine the position of the cylindrical member 24. The housing 32 may be provided with a finger receiving recess 38 in the upper end thereof so that the housing 32 may be held stationary while the blade 12 is rotated, using the thumb and third finger of the hand, Obviously,'the tool may be manipulated in any way, as found comfortable by the user.

The housing 32 is provided with an aperture 40 therein of suitable configuration so as to form a seat for a spherical indexing member 42 while preventing passage of'the indexing member 42 all the way through the aperture 40. However, the portion of the indexing member 42 that extends through the aperture 40 will engage within the spiral groove 26 in the cylindrical member 24 and thus,

due to the rotation of the cylindrical member 24 when the shank 12 is rotated, and because of the engagement of the indexing member 42 with the groove 26, the budsing 32 will advance so as to change its relative longitudinal position with respect to the cylindrical member 24. This may be readily ascertained, utilizing the magnifying glass 36 to read the indicia 28 and 30 on the cylindrical member 24 and by utilization of the indicia 44 on the housing 32 in the obvious manner.

The ball indexing member 42 is held in place by means of a clip 46 having a loop 48 receiving the indexing member 42 but not permitting passage of the indexing member entirely therethrough. The clip 46 is positioned so as to resiliently embrace the housing 32.

If it is desired, the shank of the form of the alignment tool as indicated by reference numeral 60 and as'can be best seen in Figure 8 and designated by reference numeral 62 may extend entirely through the cylindrical member of this form of the invention and through the housing 64 and may be provided with a handle 66 so that the handle may be grasped and rotated with the housing 64 held stationary by the other hand. Alternatively, the shank 12 may have its threaded end portion 16'threaded into a threaded recess 68 in the handle 70 of a screwdriver-like tool 72, or, as is shown best in Figure 10, a screwdriver-like tool generally designated by reference numeral 74 may have the tool engaging member or suction cup 18 affixed thereto in a detachable manner.

In use, when it is desired to operate the tool, the tool may be grasped in the manner as is shown in Figure 1 with the blade 14 received in the head of the screw adiustment member to be turned. Then if the indicator is in an initial position by using the thumb and third finger, the shank 12 may be rotated. This will cause the member" 42 to ride within-the groove'26. The number of @1 52? 9 9th b th s ank i w e th readily visibly determined by observation hf the indicating mechanism. utilizing the magnifying glass 36 to read the indicia 28 as; 30 n t il a? r va m mbe 2. and b utilizing th indicia 44 on the housing g1. it is to be noted (see Fig.- ure 6) the number of tirrns may be ascertained by sub,- tracting the value of the scale reading of an initial posi- ,tion from the value of the scale reading of a final posiutilizing the indicia of the scale todetermine number of turns and fractions of a turn made by the tool. from the foregoing, the constructionand operation of the device will be readily understood and further explana- ,tion1i s believed to be unnecessary. However, since noyidpus modifications and changes Will'readily occur to those skilled in the art, it is not desired to limit the in yention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents some res rt t a in vith i the s re f the a pcnded cl sf A "i i i s claimed as new is as follows:
